IM PROVEMENT IN CULTIVATORSV.

Specification forming part of Letters Patent No. 197,867, dated December4, 1877; application filed August 25, 1877.

To all whom it may concern.-

Be it known that I, IRWIN S. KRICK, of Oonneautville, in the county ofCrawford and State of Pennsylvania, have invented a new and valuableImprovement in Cultivators and I do hereby declare that the following isa full, clear, and exact description of the construction and operationof the same, reference being had to the annexed drawings, making a partof this specification, and to the letters and figures of referencemarked thereon.

Figure 1 of the drawings is a representation of a side view of mycombined cultivator. Fig. 2 is a plan view; and Figs. 3, 4, and 5 aredetail views thereof.

The nature of my invention consists in the construction and arrangementof a combined cultivator, shovel-plow, &c., as will be hereinafter morefully set forth.

The annexed drawings, to which reference is made, fully illustrate myinvention.

A represents the main-or center beam, near the front end of which, onone side, is fastened a strap or bar, B, carrying at its lower end thegage-wheel O. The upper end of the bar B is bent over the top of thebeam, so as to form a projection in the center thereof, and to thisprojection the front ends of the handles D D are pivoted by a bolt, a,which passes through slots in the ends of the handles. The handles areconnected together by a round, D, and rod b, as shown. Around the centerof the round D is fastened a sleeve, E, provided on its rear side with atubular socket, E, which is placed over the upper end of the rod G andfastened by a set-screw, cl. The rod G is permanently secured to theback of the main beam A, at the rear end, and around said rod is passeda clip, f, fastened in the usual manner, and connected by braces E Ewith the handles.

The handles D D, it will thus be seen, are rendered strong and firm, andat the same time they can be easily and quickly adjusted up and down, tosuit the height of the operator.

Near the front end of the beam A, in rear of the handle-connection, isfastened a coupling-block, H, to each side of which is hinged or pivotedthe front end of a side beam, I. The rear ends of these side beams areheld by means of hook-bolts h and nutsi to the slotted ends of across-bar, J, which is firmly bolted to the rod G, as shown. By thesemeans the side beams can be easily adjusted to any desired distance fromthe center beam and firmly held, and also be quickly removed altogether.

To the under side of the center beam A is fastened a foot, K, to whichthe breakingtooth L is fastened. This breaking tooth clears the way ofstones, roots, sod, 850., forming a channel for the point of thewing-shovel plow M to run in. The tooth L is placed at an angle, so asto cause it to draw, forcin gthe wheel 0 to press against the earth.

Adjusting the wheel 0 up or down will cause the tooth L to run deep orshallow, as required; and by the arrangement of the parts it causes thefront to stay to the ground and run steady.

The shovel-plow M is on each side provided with a hinged wing, M, and itis attached to the end of the center beam A by means of a yoke, N, andtwo bolts, 76 k. The yoke N also forms a brace, to which the slottedspreaders O O are attached by a thumb-bolt, m, said spreaders beinghinged to the under sides of the wings M, as shown.

The whole is adjustable on the beam, and can be lowered, so as to takemore earth and hill heavier, or raised so as to take less land and hilllighter when used as a cultivator and hiller combined.

Each side beam I is provided'with one or two movable sockets, 1?, eachfastened by a set-screw, n, and formed with a foot, R, to which theshovel S is rigidly secured.

The various teeth or shovels may be adjusted and arranged so as to forma threetooth cultivator, a five tooth cultivator, a marker for markingand opening for drilling corn, potatoes, &c., or a combined cultivatorand hiller, or a wing-shovel plow with the breaking tooth and wheel.

The various teeth or blades in my cultivator are formed with a centrallongitudinal or perpendicular ridge, 1), which gives a greater bevel onboth sides for the earth to pass off and also strengthens them. Thebending forward of the same, as shown, gives them abetter cuttingquality, and also strengthens them across the blade.

The teeth L and S are reversible, and each forms a broad tooth at oneend and a narrow tooth at the other end, adapting it to various soilsand conditions of soil.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the adjustable handles D D andthevertical rodG, of the sleeve E, having tubular socket E, brace-rods e,- and clip f,for the purpose hereinbefore set forth.

2. The combination, With the beam A, gage- Wheel 0, and breaking-toothL, setat an angle, of the plow M, provided with hinged Wings Intestimony that I claim the above I have hereunto subscribed my name inthe presence of two witnesses.
